Questions on Replacing Entire A/C System.
I'm replacing the entire FACTORY installed A/C system in my '85 Bronco.
Originally, the Bronco had a 302, but now has a 300, so I acquired all of the proper brackets to mount the compressor.
So, the entire system is currently installed on my new engine and in the truck.
I'll be getting 300 hoses so that things reach properly, due to the compressor being further forward on the 300 than in the 302.
I have the proper brackets from the junk yard and the entire original A/C system is currently installed.
However, almost nothing on the A/C system is any good. The condensor has dings and dents in it, and broken fins. The hoses have holes in them. The compressor is probably shot. Etc. etc. There's no belt on the compressor, and the entire system is dry.
So, I'm just going to replace the entire system front to back.
Here's my shopping list:
Drier / Accumulator
Liquid Line Hose
Suction Line Hose
Discharge Line Hose
The rest, as far as I can tell, is electronics. Is there anything that I'm missing?
What are the gotchas?
Also, what should I know about R12 vs. R134? Can I just use whichever is better?
Lastly, is there ANYTHING in this project that I should have a shop do? Or can I just put it all together, fill it with refrigerant, and off I go with frosty, cold air?
Never had A/C in my Bronco before, so this is going to be a new one.
